Abstract

1,149,910. Sound generator. SIEMENS A.G. 14 Dec., 1966 [15 Dec., 1965], No. 55951/66. Heading G5J. A sound-producing device comprises a vibrating armature 1, with return spring 1a, energized by electromagnet 3a to beat upon limb 3 of core 4. The sound volume is controlled by varying the impact by spring 2 which is adjustable by means of screw 2a. The control spring may operate in compression as shown or in tension (Fig. 1, not shown) or may be a leafspring (Fig. 3, not shown) but its characteristic must be such that the armature 1 will hit the core limb 3 at any spring setting.
